IMPROVEMENT IN- EYEGLASSES.

Specification forming part of Letters Patent No. 56,967, dated August 7,1866.

To all whom it may concern? Be it known that I EDWARD MAYNARD, ofTarrytown, in the county of West-chester and State of New York, haveinvented a new and useful lmprovementin Frames for Eyeglasses; and I dohereby declare the following to be a full and exact description thereof,reference being had to the accompanying drawings, forming a part of thisspecification, and in which-- Figure l is a view, in perspective, ofmyimproved eyeglass-frame; Fig. 2, a top-edge view thereof when opened;Fig. 3, a similar I view with the frame closed; Fig. 4, an enlargedpartial view, illustrating the mode of pivoting the bow and thearrangement of my improved stay or nose piece thereon; Fig. 5, a sectionin the line as a; of Fig. 3, showing more clearly the form andattachment of said stay-piece; and Fig. 6, a view of a different modeofopera-ting the nose or stay piece.

Similar letters indicate like parts in all of the figures.

The nature of my invention consists in the combination of a central stayor nose piece with the bow of an eyeglass-frame, which shall projectfrom said bow when it is opened, and, resting upon the wearers nose,thus prevent the glasses from tipping forward.

The frames for the eyeglasses in this my invention are best connected bya bow jointed in the center thereof, the two halves a a of the bow beingpivoted together so as to fold or swing over, as seen in Fig. 3 of thedrawings. The ends of these two halves a a of the bow terminate incircular plates, which are superimposed upon, so as to coincide with,each other, and are thus secured by a central pivot-pin, forming thejoint. With this joint so formed I combine a slender strip or nosepiece,b, of

metal, so that it shall also be held by and move upon the centralpivot-pin of the joint. (See Fig. 5.)- This nose-piece bis so bent orcurved, as seen in Figs. 1 and 5, as to reach and rest upon the wearersnose when the eyeglasses are in position thereon.

Shoulders are formed upon the periphery of the circular joint, so as toleave, when the frame is opened wide, a recess centrally at a point onsaid periphery equidista-nt from the bows just large enough to embracethe rear end, I), of the nose-piece, which is bent up to fit thereinto,as shown in Fig. 2. These shoulders allow the bow to close only over thenose-piece, which is thus embraced and inclosed between them when theyare closed, as seenin Fig. 4. Upon opening one side or the other of theframe, the shoulder upon that side of thejoint striking against the rearend of the nose-piece, as indicated in red, Fig. 4, will cause it toswing around with it until the frame, being fully open, this rest willextend out at a right angle thereto in its proper position for restingupon the nose, as seen in Fig. 2.

I contemplate insuring the adjustment of the nose-piece in its properposition by means of cogged segments 0 0 upon each end of the twodivisions of the bow, these divisions being each pivoted separately tothe nose-piece, so as that when opened the nose-piece must necessarilyextend out therefrom at right angles thereto, all as'clearly illustratedin Fig.6; and it is obvious that many other ways of attaching anose-piece to the frame of eyeglasses may be used, varying with the kindof frames employed.

I contemplate, also, the combination of the nose-piece with thespring-bow of eyeglasses when the bow is made in one piece, in whichcase 1 pivot the nose-piece thereto so as that it may be folded backover or under said bow.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

A stay or nose piece, in combination with the frame of eyeglasses,substantially in the manner and for the purpose herein set forth.

The foregoing specification of my improvement in frames for eyeglassessigned by me this 9th day of April, A. D. 1866.
